Approach for resolving unknown references with pure docutils

Docutils Users,

Currently, sphinx has an infrastructure geared toward resolving unknown
references. I have not been able to find an approach for a custom reference
resolver mentioned before on the list.

What would the best approach be for wiring in a callback to resolve missing
references with pure docutils? If it’s a transformer, when and where would
would it be added/applied? (It appears the other reference resolvers in
docutils are in the Reader).

Tony

P.S.  An aside, parsers/rst/states.py has an
unused UnknownInterpretedRoleError exception.
